## Abstract

An image forming apparatus includes an inkjet head, a blade and a cleaning liquid supply member. The inkjet head is provided with a nozzle surface on which ink ejection ports of a plurality of nozzles are opened. The blade is movable in contact with the nozzle surface. The cleaning liquid supply member supplies a cleaning liquid to at least one of the nozzle surface and the blade. The cleaning liquid supply member includes a supply hole through which the cleaning liquid is discharged, and a mesh member provided inside an opening of the supply hole and having a mesh size smaller than the opening.

## Claims

### Claim 1

An inkjet recording apparatus comprising:
an inkjet head provided with a nozzle surface on which ink ejection ports of a plurality of nozzles are opened;
a blade movable with respect to the nozzle surface while being in contact with the nozzle surface to perform a wiping operation; and
a cleaning liquid supply member which supplies a cleaning liquid to at least one of the nozzle surface and the blade, wherein
the cleaning liquid supply member includes:
a supply hole through which the cleaning liquid is discharged; and
a mesh member provided inside an opening of the supply hole and having a mesh size smaller than the opening, wherein
the mesh member has a size larger than the opening.

### Claim 2 (depends on 1)

The inkjet recording apparatus according to claim 1, wherein
the cleaning liquid supply member has a hollow space in which the supplied cleaning liquid is stored,
the supply hole is communicated with the hollow space, and
the mesh member is attached on a bottom surface of the hollow space.

### Claim 3 (depends on 1)

The inkjet recording apparatus according to claim 1, further comprising:
a cleaning liquid supply mechanism which is disposed separated away from the inkjet head and supplies the cleaning liquid to the cleaning liquid supply member, wherein
the cleaning liquid supply member is supplied with the cleaning liquid from the cleaning liquid supply mechanism, is then separated away from the cleaning liquid supply mechanism and moved to a position where it can be in contact with the nozzle surface while holding the supplied cleaning liquid.

### Claim 4 (depends on 3)

The inkjet recording apparatus according to claim 3, wherein
the cleaning liquid supply mechanism includes a cleaning liquid tank for storing the cleaning liquid and a pump which pumps the cleaning liquid from the cleaning liquid tank and supplies the cleaning liquid to the cleaning liquid supply member.

### Claim 5

An inkjet recording apparatus comprising:
an inkjet head provided with a nozzle surface on which ink ejection ports of a plurality of nozzles are opened;
a blade movable with respect to the nozzle surface while being in contact with the nozzle surface to perform a wiping operation; and
a cleaning liquid supply member which supplies a cleaning liquid to at least one of the nozzle surface and the blade, wherein
the cleaning liquid supply member includes:
a supply hole through which the cleaning liquid is discharged; and
a mesh member provided inside an opening of the supply hole and having a mesh size smaller than the opening, wherein
a plurality of the mesh members is overlapped.

### Claim 6 (depends on 3)

The inkjet recording apparatus according to claim 3, further comprising:
a wipe unit including the blade and the cleaning liquid supply member, wherein
as the wipe unit moves, the blade and the cleaning liquid supply member are moved.
